LANns, AND o'NE-EQUETH l NETHERLANDS.

T all when@ it concern.' s -Be it known that I, PIERRE THEoDoRE ALBERTLAssoHUIT, a subject of the Queen.l

or the Netherlands, residing at Generaal Cronjstraat ,'15, Schoten, nearHaarlem,

, Netherlandsphave invented acertain-new and useful Improvement inGas-Burners, o which the following is1 a specification.

The present invention contemplates anl improved burner which visprovidedwith a regulator; for air and so constructed as to obviate the'defects usually associated with' gas burners suitable for use with gasatvordinary pressures of supply and o 'f a greater diameter than 10centimeters. 'By this ,'aI-l rangement a complete mixture of the-gas andair is producedyas also-"a thorough and even distribution' of,V themixture over the entiresu'rfaceof. the burner, while itis possible* togive; the surface of -theh-urner a v`much 'greater diameter than hasr,been the case heretofore and'at the same timel to-con sume the gas atlthe ordinary pressure. Moreover with this burner individual adjustmentsof the gas and air supply are not v possible; by means of'a commonadjustment the same proportion can always be had. n

l The vinvention will now be described With referencel to theaccompanying drawings illustrating an'ernbodiment of the invention andinwhich':

.Figi'irel is aside view,'partly in section of a gas burner constructedaccording to the present. invention; Fig. 2'. is 'a longitudinallsection of the gas'and air regulator, Valong the line A B Vof Fig 1;Fig. 3 is a plan of thepartially covered chamber-or compartment for themixture of air and gas. Fig. e' is; a detail of' the' revolvingplate,'z'wl1ich covers thechamb'er.

The chamber 0 is'partially' coveredv by the solid sectors 2jand l (seeFig.' 3),-and theair maybe admitted through the open seyes "tors l and3;

A revolving' plate e f(Il ipgfill) is. divided into-sectors 1.', 2.', 3and', vcorrespond-mg to the sectors 1, 2, 3 and 4 of the airchamf'bei-and is adapted to cover the latter.; this plate can be,rotatably'ad-justed around the 'llame of. equal sizethroughout.

The 'complete'mixture of gas and air.

Specification of Letters Patent. Ptenied July 20., 1915 Application'filed October 25, 1913. SerielvNo. 797,210.A

`'screw In... Of thisvplatee the sectors 2. and 4 are open and 1 and 3are closed.' It is evident, that by turning theplate e the open sectors1 and 3 of the' chamber c can be pararrangement: employed produce acorrespending and simultaneous adjustment of the cock andpla'te e. Thearrangement moreover is such that the sectors-1 and 3 completely7 -coverthe air openings land 3-of the chamber when the. cock is completelyclosed'and leave them'entirely open, when the cock isrentirely open. 'Bythis arrange ment a maximum supply of air is furnished simultaneouslywith a maximumsupply of' `gas, and thesupply 'of air is completely; shutolfwhen the supply of gas ceases, while in the 'intermediate pp sitionsthe degree of opening or closure o'f'the'cockY Yand the correspondingopenings Yor sectors for theV supply of air, iare in definiterelation,'so that with anyadJustment the supply of air is always 'fproperly proportioned -to the supply of gas. advantage ari-sing fromthis construction isthat the supply of air ent/ens the chamber from thetop.

The' gas lthat has enteredl through the-inlet a into the chamber, by itstendency to rise, immediately comes into contact with the airlthat-.streamsthrough openings in the'upper Apart offsaid chamber, so.that 'acomplete mixture takes place4 which produces a hot leaves thechamber by thecqnducting .tube (Z and passes to th burner-head, whichmay be constituted bya circular box 'm with a cover 'nl (which'-may bedetachable)l,"formed .with perforations'p throughA which the gas issues.and -it is this upper surface thatforms the real surface `of the burner.l

. To the end ofthe mixture -supply tube. is

ixeda conical orother appropriately shaped Covering o which projectsinto the burner head andisformed with rows of small perforations 1through which the mixtureof gas v'air streams on passmg into the burnerhead'. By Vvirtue of this so-called gas distributer, an equaldistribution of the mixture is obtained on the surface of the burner,

so that the flame spreads over the Whole burner and has in every part ofit the same degree of heat.

.reason of the complete and intimate .mixture ofthe gas with the air;and moreover by virtue of equal distribution of the mixture on thesurface of the burner, incrustation and the formation of soota'reentirely prevented.

lVhat claim is:

A gas burner comprising a burner head, an air and gas mixing chamber, agas inlet leading to said. mixing chamber said gas inlet' being disposedin a horizontal plane,

Copies of this patent may be obtained for a conducting tube leading fromsaid mixing chamber tosaid burner head, an air inlet located above themixing chamberand at right angles to the gas flow, and means forcontrolling simultaneously the supply of proportional quantities of gasand air to said mixing chamber comprising a rotary gas cock controllingthe said gas inlet; a rotary air valve controlling the said air inlet;the said gas cock and air valve being located one behind the other andeachrotating around an axis perpendicular to the gas How; and meansconnecting together said gas cock and said air valve, said vconnectionbeing' such -that the gas cock and air supply valve simultaneously4describe equal angles about their axes. f, f

In testimony whereof, have signed my name to this specification in thepresence of two subscribing Witnesses.
